The former Kerio Valley Development Authority (KVDA) managing director David Kimosop has been arrested.
Mr Kimosop was detained on Friday morning at the Jomo Kenyatta International Airport as he returned to the country from Kinshasa in Democratic Republic of Congo through Tanzania.
Mr Kimosop was the only big-name suspect in the Sh63 billion Kimwarer and Arror dams scandal who was yet to be arrested.
Other key suspects are former Treasury Cabinet secretary Henry Rotich, former principal secretaries Kamau Thugge and Susan Koech, and National Environment Management Authority Director-General Geoffrey Wahungu. They were charged and released on Tuesday.
At the time, Mr Kimosop’s lawyer Katwa Kigen requested the court to give him more time to present his client for plea-taking because he had travelled outside the country.
“David Kimosop travelled to Congo and he was supposed to have landed on Saturday,” Mr Kigen said. “I requested him to come earlier and he said that by Thursday he shall have landed. I am requesting to present him on Friday for the plea.”
